Server chronicles - another repair

 The entropy can only increase, so after some time I had the server shut down, when I restarted something went wrong.
I didn't notice any problem until I did walk close to it.
I did see the Red LED blinking, indicating a problem.

HA - HomeSeer - connect UPS via APCUPSD

It is very useful to have the hub (HomeSeer in this case) connected to an UPS.

Small outages will not disrupt the normal working and in case of long blackout will be possible to safely shut down the system.

Plus will be possible to create events to inform about an outtage, like sending an email.
This article uses the plugin APCUPSD that is not free and is based on the apc utilities.

HA - HomeSeer - connecting to an UPS via NUT

My Meshstastic - what for ?

So .. Meshstastic is nice, I'm starting to acquire HW for different nodes and experimenting but is also time to plan what to do with it, on the long term.

There are many possibilities but in the end my goal would like to be :

• set up a private network to stay in contact with family/extended family
• have a way to stay in direct contact for activities like hiking
• have access to some environmental data
• have access to the HA system remotely
• routing

Server chronicles - testing fan proposal

The HP ProLiant DL360p Gen8 has 8 fans to cool down the two CPUs and other hardware.

These fans are high speed PWM controlled and are prone to fail over time.

The only thing to do is to replace the defective fan with a new one, but it would be nice to understand exactly what the problem is and check if the replacement fan is working before to open the server.

Home Assistant - evaluation

Recently I started to experience problems with HomeSeer.
My Homeseer HomeTroller (basically a Raspberry Pi) started to experience constant crashes.

In the end is the mono environment very critical, a plugin with problems, a service below not working properly, and mono crashes.

So I started to search for alternatives to HomeSeer, because spending more money on a platform that anyway is faulted, doesn't make any sense.

Evaluating a device

I love to go to antique mall and flea market and look to find pieces of technology to play with.

In one of my tour I did find in very good conditions an Anviz FacePass Pro 7, a clock-in face recognition device for few $.

Let discover what it is, if is working and how I could use it !

Repairing an electric curtain

Once again, I did find in a flea market for few $$ something that interested me : an electric curtain.

It was still sealed (apparently) and everything supposed to be in it, it was.

But of course ... it was .. it is, broken.

Let see if it can be fixed. If not ... well, is a very good source of interesting components !
